hereby decline that the following is nfull, clear, and exact description ofthe construction and operation of the same, reference hein hndthe annexed draw ings, andthe letters of reference marked thereon, makinc' a part of this specification, in whichl-` l1igure. 1 is a perspective `view.

' Myginachine is built on threewheels, two large bur- "lhe small or guide-wheel F is connected with axle 4'.l'byaifranie, D, shaped like the letter A. Said guidewheel is a caster, andthe crotchcd shaft passes up through thefront of frame D, risinghighenough to receive guide-lever, G.

' Rising from the vertexof frame 0 is a sight-post, V.

" On thefront part of frame D is a platform, E. In.

the centre ofplatiorm E, I'contempiate asecond sight Frame D allowraxle B to revolve in the ,sidehars thereof.

01'1 the axle B, and over frame D, is` placed frame O, nearly baiancedrand playing freely on said axle.

` The front bar of vframe O is connected with the crossi 'hat'` of frame D by a screw, H, used foelevate and depress the front oi' frame O. The side-bars of frame O vare.'prolonged to rear of the 'fiamopen Between V,Through said hollow shaft, an rough the sidebarsof'ii'ame C, is passed a solid shait, W, secured to said hollow shaft by a pin, X. Cast oh, or otherwise secured Vto said hollow `shahnis, any required number of disks, (in this ,machine nine,) marked L.

' Secured to these disks are eight cutters, the main working-part of the improvement, and may be called plows. They are formed by a stxapof steel, three inches wide, brought into the shape of three sides of afrectangle, one foot ioni,r andeghtinches Wide.

The open end of 'this cutter is tur-'ned to said shaft, and'th'e ends of the two long'sides attached to two. djoiningidisks by dovetails and screws, or otherwise.'

.Said cutters are distributed around said shaft, at anv angle ot'ibrty-iive degrees to each other.

The sfhort side of said 'cutters makes the under-eut .of each slice, and may be called the. share. The paralle! sides, especially ythe let'nrmtmake the perpenrlicular cut, and may he called thecoulters.

The edge of thel share, in my'drawings, is'straight, and withr the straightcdgved share I-dernonstxated the power of reaction to propel thecarage when the working-shaft is driven by a'spriug on a platform on said I havecontemplad, for field-machines, a share with edge shaped like the letter V, with the vertex forward, and also a set of pointed instruments, with eyes like a mattock, for tramped or gravelly earth. The'shares should he curved in the line of motion, to about the same arc as the line of motion around the shaft. The width and curve of share should be greater for an engine of low speed than high. The edge of the share should be further from the shaft than the back, as it travels while it revolves. Each cutter cuts eight inches in width and depth, and, is'marked M. Allpexcept the Aright-hand one, eight and a half inches clear in wldtll,"that the slice may* pass freely through. The

second extendshalf an inch into the furrow inade by the lirst.- The third, over the second, and so of the rest.

To the left side of the lett disk is secured an eccentric, N, hy screws, or otherwise, and to said eccentricV a scc'ond eccentric, N, to receive connecting-rods from.

the .pistons/ofanysuitable double engine, placed cnf flame O.

It has been ya leading obJect with mel so to combine and arrange the parts of my machine as to receive the power of the engine directly from lthe piston,.on the shaft carrying the cutters, thuspassing the power to the main work, without waste, on intervening gearing. Thus, too, thc, reaction is thrown back on the carriage, without intervening machinery, as a propel-1 ing-power in the line of tiavel.

On theleit end of solid shaft W, is pinion K, fou inches diameter, workin into spur-wheel G, twentyfou-r inches diameter. n the same shaft with spurwhcel O, cast solid with said wheel, is pinion P, ten inches diameter, working into a cog-rim, cast on or otherwise secured to the left burden-wheel, said cog@ rim, forty-two inches diameter. Q, burden-wheel, fortyeight inches diameter.

Icall the combination, made up of the hollow shaft,

K, the working-shaft. Said shaft receives the power directlyfrom the engine, applies it directly to the mairiV c work, and sends the resulting reaction directly to the carriage in the precise'line of travel, and, through the gearing, transmits any required power, if reaction he not suiiicient, to travel the machine to its feed of six inches. t'o the revolution. The left burden-wheel, re-

ceiving motion from the gearing, ca rics axle B, and,

The lock is eected bysnid letcrilling' under catch pins U, on the perimeter ot said wheel.- When collar R is shipped with said whel, they revolye with axle B. When unshipped, the collar revolves-svith said axle, and said wheel stands still. Lever S is secured in position by catch 'L Said right wheel, when unshpped, is held from sliding from the inner bar of frame O, by pin Y., l

lo loperate my machine, steam beingr up, the engineer ou platform O, with his box of fuel 'and barrel or keg of water, hy the screw H lifts his cutters above ground. If he is in position for plowing, sees that right wheel is shipped, turns on steam gently, so as to make the under stroke ofthe shares a back` stroke. Then, as near as may be, simultaneously 'lets the shares into the earth, andets on full steam. To keep himself accurate in liue,hewatches sights,and, if need s be, works guide-lever G. If he needs to turn his machine, he comes to a'siow motion, unships and locks right burden-wheel, when the whole machine revolves on said wheel as a centre, turning to the right.' The stroke may be reversed, and turn to the lcit, by back ing. In either way bring the sights to the desired line, reship, and move forward.

The' first revolution, the cutters cut a slice, which is the segment of a cylinder, eight inches wide, twentytwo and one-third long, and eight inches thick in the middle. During the revolution, the machine tiaveis forward six inches to the feed.

After the rst revolution, each cutter takes a slice somewhat wed e-shaped, fourteen'inches long, with an oblique h of surface-earth, eight by six inches, which slice is carried back and dropped with the snrface-end in the bottom ofthe pit from which it is cut,

and the subsoii-end overlapping the preceding slice. Said slice fourteen and one-third inches in length, though only partially reversed, amply buriesnnder the suhsoil all the sod or surface-earth.

It will readily be seen that no motion is given this soil to the right, cr lett, or forward, the whole action of the cutters on the earth being rst obliquely downward and backward, curving to a horizontal line, and

the last three inches of cutting slightly upward. This motion results in' reaction forward and slightly upward, the most advantageous line ofl action for propellingpower on a machine travelling over a yielding surface.

It will be readily seen, also, that the engine, being brought to bear' directly on.- the wcrkingshaft, exerts ing, do .the saine work with a slower engine and the same travel, while a machine'ofdonble the width of swath would do the same work at half-mile travel, or double the work at the sarn'e speed.

Most of the parts et' my machine have equivalent devices, long in use, but 'the'combnation, the process,v and the eil'ect are new. Numerous substitutions may he made. A crank and pinion vfor the screw E. "The hollow shaft may be dispensed with, by placing'rnovable half-disks dircctlycn 'the solid shaft. The right burden-wheel may be otherwise .nnshipped IH I have contemplated the extension ofthe reacends of the side-hars of the frame Q, thejengthening of the arms of the cutters, and 'a proportionate alteration in thegearing, so as totales-any required depth cfsiic'e.

. 1. I claim as new` in steam-plowing, the working shaft, andthe combination :and arrangement by which said shaft is placed inpesitionfto receive hthe power direct from the engine, with the friction of a sin'gie axle between the engine and themai work of moving earth.

2. I claim the frame, 0, and the mode of raising and lowering the working-machinery as desired, by said frame and the screw H.
